Ubisoft has revealed its post-launch "roadmap" for Assassin's Creed Odyssey DLC content and it makes for very interesting reading. For one thing, the game is shifting to an episodic format for additional story material with two new storylines which will each consist of three instalments. Even more interesting is the news that the game's $40 Season Pass will also include a fully remastered version of Assassin's Creed III.

The first DLC story arc is Legacy of the First Blade, and will feature "the first hero to wield the iconic hidden blade". Given that Odyssey is set hundreds of years before the adventures of Bayek of Siwa, this promises to extend the Assassin's backstory even further into prehistory.

The second story arc is The Fate of Atlantis, but sadly won't feature Indiana Jones. Instead you'll encounter "godly creatures" and uncover "the secrets of the sunken city". This storyline promises to be even more essential for fans of the franchise's deep lore, with hints that Atlantis is connected to the First Civilization and presumably involved in scattering all those pesky Eden relics around the world.

Interspersed between the DLC episodes will be The Lost Tales of Greece, an ongoing buffet of free story content which adds new quests to the core game over time, some involving characters already introduced in Odyssey, others introducing new characters. There will also be weekly in-game events featuring Epic Ships and Epic Mercernaries, who will offer high level gear when you take them down, and special Contracts that will reward you with an exclusive in-game currency to spend at a special merchant.

The first chapter of Legacy of the First Blade is due in December, with the first episode of Fate of Atlantis landing in spring next year. New episodes are expected to launch on a roughly six-week-long schedule, meaning there'll be regular new Odyssey content well into summer 2019 and beyond.

Assassin's Creed Odyssey launches on October 5 for PlayStation 4, Xbox One and PC. In Japan the game will also be available on Nintendo Switch, using cloud streaming. Capcom tried something similar with Resident Evil 7 but as with that experiment, don't hold your breath waiting to see if it comes to the west.
